Manufactured in Germany, each piston is forged to deliver superior strength and efficiently dissipate heat from the combustion chamber to the cylinder walls. The piston's elliptical design is crucial for maintaining a uniform bearing surface during thermal expansion, which helps to prevent localized pressure points and potential piston collapse. This results in a more reliable and durable engine component.\n\n### Key Features\n\n\t\n- Forged Piston: Provides exceptional strength and extends component life.\n\t\n- Heat Dissipation: Designed for efficient thermal transfer, crucial for engine cooling and performance.\n\t\n- Elliptical Design: Ensures even load distribution during expansion, minimizing stress and wear.\n\t\n- German Manufacturing: Built with precision and quality from a leading European manufacturer.\n\n### Specifications\n\n\t\n- Bore Size: 67.25 mm\n\t\n- Actual Piston Diameter: 66.19 mm\n\t\n- Displacement: 246 cm&sup3;\n\t\n- Stroke: 72.00 mm\n\t\n- Clearance: 0.06 mm\n\t\n- Compression Height: 38.00 mm\n\t\n- Wossner Compression Ratio: 2-stroke\n\t\n- OEM Compression Ratio: 2-stroke\n\n### Component Part Numbers\n\n\t\n- Wossner Piston Part Number: 8156D125\n\t\n- Lock Part Number: CW18\n\t\n- Pin Part Number: WP033\n\t\n- Ring Set Part Number: RSB6725 x2","weightGrams":null,"fitments":[{"make":"HONDA","model":"ATC R 250","cc":null,"notes":null,"years":"1985–1986"},{"make":"HONDA","model":"CR 250","cc":null,"notes":null,"years":"1984–1985"},{"make":"HONDA","model":"TRX 250","cc":null,"notes":null,"years":"1985–1989"}],"collections":[{"name":"Engine","url":"https://www.2brosparts.com/api/agent/collection/GB/engine"},{"name":"Pistons & Kits","url":"https://www.2brosparts.com/api/agent/collection/GB/pistons-kits"}],"links":{"page":"https://www.2brosparts.com/products/piston-kit-84-85-cr250-6725-wossner-8156d125-honda-mx","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/d0e97d910c82:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/d0e97d910c82:1"}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
